Nei uchifanira kuvhara negoridhe rePCB?

1. Pamusoro pePCB: Osp, Hasl, Hasl Hasl, nyonganiso tini, ention sirivha, yakaomeswa goridhe kune yakazara bhodhi, goridhe, enpig ...

OSP: Mari yakaderera, yakanaka yekushanda, yakaoma mamiriro ekuchengetedza, nguva pfupi, tekinoroji tekinoroji, yakanaka tekinoroji, yakatsetseka ...

Hasl: Kazhinji ndezvekuwanda HDI PCB samples (4 - 46 matanda), yakashandiswa nezvakawanda zvekutaurirana, makomborero, midziyo yekurapa uye mabhizinesi ekurapa uye zvikamu zvekurapa uye zvikamu zvekutsvaga.

Chigunwe cheGoridhe: Iko kubatana pakati peiyo memory slot uye chipy memory chip, zvese zviratidzo zvinotumirwa nemunwe wegoridhe.

Chigunwe cheGoridhe Isconsists yehuwandu hwehuwandu hwegoridhe hwekuita, izvo zvinonzi "chigunwe chegoridhe" nekuda kwegoridhe-yakaiswa pamusoro pegwenzi uye zvigunwe zvadzo zvakafanana. Chigunwe cheGoridhe chaicho chinoshandisa chiitiko chakakosha kuCoat mhangura negoridhe, iyo inodzivirira zvakanyanya kune oxidation uye maitiro makuru. Asi mutengo wegoridhe unodhura, iyo yazvino tin plating inoshandiswa kutsiva ndangariro yakawanda. Kubva muzana ramakore rapfuura 90 S, zvinyorwa zveTini zvakatanga kupararira, mrinboard, uye mongano yegoridhe "ingangoita servers

  1. Nei uchishandisa iyogoridhe plating bhodhi?

Nekubatanidzwa kwe iC Ipo iyo tini yeTIN yekupuruzira yakaoma kupururudza iyo yakanakisa tlar, iyo inounza kuoma kuti smt kukwira; Mukuwedzera, hupenyu hwesherufu hwe tint spraying ndiro ipfupi. Nekudaro, ndiro dzegoridhe dzinogadzirisa matambudziko aya:

1.) Yekodhi yemufumboo yegomo, kunyanya ye0603 uye 0402 Ultra-yegwendefa rewadhi rekutengesa, saka, iro goridhe rakanyanya kuwanda.

2.) Mukutonga kwezvinhu, pesvedzero yezvinhu zvakaita sezvinhu zvinowanzoita kuti ushandise mhou dzerwendo ruchakurumidza kusvika, Kunze kwe, goridhe-rakarongedzwa PCB mumadhigirii emutengo weiyo sampule nhanho ichienzaniswa nepepuru pepamba

3.)

4.) Asi uye neakawanda uye zvimwe zvinoshamisa zvekushandisa, mutsara upamhi, kupatsanurwa kwasvika 3-4mil

Naizvozvo, zvinounza dambudziko redunhu pfupi yegoridhe yegoridhe: nekuwedzera kwegoridhe kwechiratidzo, pesvedzero yekushambadzira kwekutapurirana kwejasi rakawanda nekuda kweganda rinowedzera uye rakajeka

  1. Nei uchishandisa iyoImmersion Gold PCB?

Kune mamwe maitiro eiyo akanyudzwa goridhe PCB inoratidza sepazasi:

1.) Chimiro chekristaro chakaumbwa negoridhe uye goridhe rakasiyana, ruvara rwegoridhe rakanyudzwa ruchave rwakanaka kupfuura goridhe racho uye mutengi akagutsikana. Ipapo kushushikana kweiyo yakadzika goridhe ndiro iri nyore kudzora, iyo inokodzera kugadzirwa kwezvigadzirwa. Panguva imwe chete iyoyo, nekuti ndarama yakanyoroveswa kupfuura goridhe, ndiro dzegoridhe dzisingapfeke - kupokana negoridhe munwe.

2..

3.) Iyo Nickel Goridhe Inongowanikwa pane iyo Poig PCB, chiratidzo chekushambadzira muganda chiri muganda, izvo zvisingazoite chiratidzo, zvakare huro mutungamiri wengoridhe waya. Murwi wedunhu anounganidzwa zvakasimba pamwe nemhangura matare.

4.) Iyo crystal chimiro chegoridhe inomerener inokwenenzvera kupfuura goridhe irikugadzirira, zvakaoma kuburitsa oxidation

5.) Iko hakuzove nemhedzisiro pane kupatsanurwa kana muripo wakagadzirwa

6.) Kubata kumeso uye hupenyu hwebasa kweiyo ndiro yegoridhe kwakanaka senge kwegoridhe ndiro.

 

  1. Kunyudzwa goridhe vs goridhe plating

 

Kune marudzi maviri egoridhe-goridhe tekinoroji: imwe gadziriro yevagetsi yegoridhe, imwe yacho iri kunyudzwa goridhe

 

Nechero chendarama, mhedzisiro ye tini yakaderedzwa kwazvo, uye mhedzisiro yegoridhe iri nani; Kunze kwekunge mugadziri anoda kusungirwa, kana zvino vagadziri vazhinji vachasarudza iyo goridhe kunyura maitiro!

Kazhinji, kurapwa kwepamusoro kwePCB kunogona kukamurwa mumhando dzinotevera: Electroplating, SILENTION LINE (INS SILATE), Pasina-mahwendefa. Pamarombo emurombo (kudya tini murombo) izvi kana kubviswa kwevanogadzira maaira uye zvekugadzirisa zvinhu.

Pane zvimwe zvikonzero zvePCB dambudziko:

  1. Munguva yekudhinda PCB, ingave paine mafuta anoparadza firimu yepasi pani, inogona kuvhara mhedzisiro yeTini; Izvi zvinogona kuvimbiswa nemutengesi anofamba bvunzo

  2. Kunyangwe chinzvimbo chepombi chinogona kusangana nezvinodiwa zvekugadzira, izvo, kunyangwe iyo Pading Pad inogona kugadzirwa kuti ive nechokwadi chekutsigirwa nezvikamu.

  3. Pad haina kusvibiswa, iyo inogona kuyerwa ne ion kusvibiswa; t

Nezve pamusoro:

Goridhe irikugadzirira, inogona kugadzira PCB nguva yakareba, uye nekunze kwemamiriro ekunze ekushongedza uye shanduko yezvinhu zvidiki (zvichienzaniswa nedzimwe kurapwa kwepasi), kazhinji, inogona kuchengetwa kweinenge gore; Hasl kana kutungamira yemahara hasl pamusoro pekurapa chechipiri, Osp zvakare, iyo maviri ekurapa mumamiriro ekunze ekunze uye yekunyorovedzera nguva yekuchengetedza nguva yekuteerera kune yakawanda

Mumamiriro ezvinhu akajairika, kurapwa kwesirivheri kwakasiyana zvishoma, mutengo zvakare wakakwira, mamiriro ekuchengetedza anonyanya kudiwa, kukosha kwekushandisa pasina sulfu mapepa ekugadzirisa! Uye uuchengete kwemwedzi inenge mitatu! Pane iyo tin maitiro, goridhe, op, tin that spray iri pamusoro peiyo, vagadziri vanonyanya kufunga nezvekuita kwemutengo!
